WC module with WC bowl forming part of wall construction

ABSTRACT

A WC module which is ready to be installed into place and to be connected to the water and sewer connections is described. The module has been formed so that its inner wall and WC bowl are of the same piece. Above the WC bowl are situated seat boards which are fixed to the inner wall by a hinge so that the seat boards can be turned into an upright position when they are not in use. The module is formed of two elements in the rear part of which are situated the technical devices relating to the functioning of the WC module, such as the WC bowl, the water tank, etc., and the front part of which incorporates a door.

BACKGROUND OF THE INVENTION

The present invention relates to a WC module which can be installed inany public premises, such as a railway station, airport, market placeetc. It can also be installed, for example, in connection with a shipcabin., as WC premises.

According to a known method, WC modules are constructed so that all thefixtures required, such as the WC bowl, washbasin etc are alreadyinstalled in the WC premises at the factory. Thus, at the installationsite these fixtures only need to be connected to the water pipes andsewer. Thanks to the preliminary work carried out at the factory,significantly less valuable installation time is spent on constructingthe WC module on site.

Despite the work done at the factory, however, WC premises have notbecome simpler. All fixtures still require their own space in the WC.Due to the complexity of the premises, cleaning them is alsoinconvenient.

SUMMARY

An object of the present invention is, therefore, to achieve a WCmodule, which is essentially simpler than present premises and thus alsomore efficient in use and easier to clean. According to the invention,the module does not have a separate WC bowl, but it is incorporateddirectly as a continuation of the wall structure of the module. Thus,the WC no longer has to be made of separate components. The design andstructure of the WC module relating to the invention incorporates allthe equipment necessary in a WC.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

FIG. 1 shows a partly cross-sectional view of the WC module 10 relatingto the invention. The figure shows that the module does not comprise aseparate WC bowl 11. Instead, the inner surface of the module 10 isdesigned so that the WC bowl 11 is a direct continuation of the curvedwall surfaces 12. The bowl 11 is flushed by running flushing water fromthe nozzles 13 on the wall 12 down the wall surfaces into the bowl 11.The water tank 29 can be situated in the upper part of the module,hidden behind the curved inner wall 12.

The module 10 does not comprise a traditional, fixed WC seat for sittingon either, because the WC bowl is an integral part of the wall. In theWC module relating to the invention, the WC seat is arranged so that onthe rear wall of the module 10, there are seat boards 15, which areturned down on a hinge 14, and rise up again after use. Above the seatboards 15 is a toilet paper roll rack 16, because the toilet paper isalso used as covering for the seat 15. The paper is, therefore, insock-like form so that it can be pulled over the seat boards.

A handle 25 and a light fixture 26 are connected to the inner surface 12of the WC module 10, and on the floor level a floor drain is formed,which is covered by a grating 17. A separate water feeder is led to thefloor drain, which feeder flushes the space below the grating 17 at thesame time as the WC bowl 11 is flushed.

FIG. 2 shows the WC module of FIG. 1 as seen from the front. It alsoclearly shows how the WC bowl 11 is a continuation of the curved walls12. The flushing water is fed from nozzles 13 along the walls 12 intothe bowl 11 and further on to the sewer 18. In this example, the nozzlesare separate elements, but it is also possible to make a fold or otherprotrusion in the wall, which can as such act as a flushing waternozzle. The floor drain below the floor grating 17 is also connected tothe sewer through opening 19.

The water tank 29 is shown in the figure by a broken line, and the waterfeeder pipe 30 projects downwards from it. The flushing water flowsthrough a feeder valve in the wall, through the pipes 31, to the nozzles13. FIG. 2 shows the panel 27 of the feeder valve which comprises ahandle for flushing the WC bowl and a handle for the handwashing tap 28.Besides being flushed by means of a manual handle, the WC bowl flushingcan alternatively be made automatic, so that whenever the seat boards 15rise up, the WC bowl is flushed. The floor drain under the floor grating17 would in that case also be flushed.

The WC seat consists of two seat boards 15, which are upright againstthe wall, below the toilet paper roll rack 16, when they are not in use.The figure shows that the upright storage position of the WC seat 15 hasanother function as well. Since the toilet paper 20 has been made into atube, tubular covers can be pulled over the seat boards 15 from twoseparate toilet paper rolls. Cutting perforations are formed in thetoilet paper at about 50 cm intervals. When the excess paper has beencut off, the seat 15 can be turned on the hinge 14 into the lowerposition, which is marked by reference number 21.

The raising of the seat 15 can be effected either by means of acounterweight or by a spring. It is advantageous arrange a short delayin the raising, so that the seat boards 15 are not raised too soon.

FIG. 3 shows the structure of the WC module relating to the invention asseen from above. The WC consists of two elements, which are the rearpart 22 and the front part 23. All the functions and technical devicesof the WC module are situated in the rear part 22. The front part 23only comprises the door 24. This division is appropriate, firstly,because in this way all connections can be situated in the same placebehind the module. Secondly, from the point of view of mouldingtechnique, it is advantageous to make the curved parts 22 and 23separately as shown. Thirdly, formed in this way, elements 22 and 23 aremade sufficiently small so that they fit through the doors of alreadyexisting WC premises. This is significant when a WC is to be renovatedby installing a new WC module relating to the invention in old premises.

The design of the WC seat 15 and of the other details of the module 10may obviously vary. The exemplified embodiment is designed to be made ofreinforced plastic.

FIG. 4 shows diagrammatically the movement of the seat board 15 in theWC module. Hinge 14 may be situated on the rear wall of the module, asshown in the above figures. According to the embodiment shown in FIG. 5,the hinge 14 can, however, also be situated on the side walls, in whichcase the lifting movement of the seat boards 15 takes place in adifferent direction. The essential aspect is that the seat boards 15 arein their upright position directly below the toilet paper container 16,so that the cover paper can easily be pulled over the seat boards.

An essential part of the basic idea of the WC module relating to theinvention is in fact its hygiene. It has no hollows, which might easilycollect dirt. In principle the WC can be used without touching anythingwith the bare hands.

The hygiene is achieved through the advantageous structure and efficientfunctioning of the devices. An important part is also played by thetoilet paper relating to the invention, the cross-section of which isshown in FIG. 6. The paper is folded into a closed tube, which is seamedat point 32. The seam 32 can also be on the side, as shown in FIG. 7.According to the third embodiment shown in figure 8, the toilet paper 20can be made in advance to consist of two parts. In this case there aresimilar seams 32 as in FIG. 7 on the sides, but also perforations at theseam 33 in the middle of the paper web, so that the wed can easily bedivided into two tubular strips.

It is obvious to a person skilled in the art that the differentembodiments of the invention may vary within the scope of the claimsgiven below.
